From: Adsorption of phosphate in water using one-step synthesized zirconium-loaded reduced graphene oxide
(a) Adsorption of phosphate on RGO-Zr at variable low initial phosphate concentrations (adsorbent dosage = 0.025 g/L, pH = 5.00 ± 0.20, temperature = 298 K). (b) Adsorption of phosphate on RGO-Zr at different high initial phosphate concentrations (adsorbent dosage = 0.20 g/L, pH = 5.00 ± 0.20, temperature = 298 K). The pseudo-second-order kinetic curve fitting for: (c) low initial phosphate concentrations and (d) high initial phosphate concentrations.
